Top domains cited by AI search

From tens of millions of sources: Reddit, YouTube, LinkedIn, Wikipedia, and review sites keep winning — with platform twists.

Mar 31 2026

AI doesn't invent citations from nowhere. Across large multi-engine samples, a familiar cast dominates: Reddit, YouTube, LinkedIn, Wikipedia, Forbes, G2, Yelp, Facebook, Medium, TechRadar.

Platform twists

  • Google AI Mode / Overviews: heavy YouTube + social (Facebook, Yelp)
  • ChatGPT: Wikipedia, Reddit, Forbes, TechRadar, LinkedIn
  • Perplexity: Reddit, YouTube, LinkedIn, Wikipedia, G2

What to do

Maintain authentic Reddit and YouTube presence (review transcripts). Treat LinkedIn executive posts as citable artifacts. Keep review profiles accurate. Diversify — Reddit blackouts have happened before.

Then ignore the generic top 10 and open Anny's domain view for your prompts. Hotels aren't SaaS; your Booking.com equivalent matters more than Medium.
